Technical Field

[0001] The invention relates to the technical field of silicon material processing feeding equipment, and in particular to a feeding device for silicon material processing. Background Art

[0002] In the process of silicon material processing, the feeding device is a crucial link. Traditional feeding methods mostly rely on manual operation, which is not only labor-intensive and inefficient, but also difficult to ensure the accuracy and stability of feeding. With the development of automation technology, more and more automatic feeding devices are used in the field of silicon material processing.

[0003] Although the existing automatic feeding device has improved the working efficiency to a certain extent, there are still some problems. For example, the traditional conveyor belt feeding method has scattered drop points during the transportation of silicon materials, and the silicon materials are easy to roll and fall off during transportation, which affects the accuracy of silicon material feeding. At the same time, due to the large size of the conveyor belt equipment, when the material is deviated during feeding, it is extremely inconvenient to adjust. Therefore, a feeding device for silicon material processing is needed to solve the above problems. Summary of the invention

[0010] Preferably, the blade is designed to be inclined, the bottom end of the bucket tube guide groove is designed to be an inclined surface, and the left and right blades are symmetrically arranged.

[0014] The present invention has at least the following beneficial effects: 1. By setting up negative pressure suction equipment, anticipation equipment and screening components, stable suction and feeding of silicon materials can be achieved. Compared with the traditional structure, this device starts the negative pressure suction cylinder through the negative pressure suction pump to form a suction negative pressure, and sucks the silicon material in the hopper through the transmission pipe. When the silicon material remains to a suitable amount, the beam plate is flipped open to carry out the unloading operation, ensuring the accuracy of the loading of the processing equipment. At the same time, the bucket can filter the impurities in the silicon material to ensure the uniformity and quality of the size of the silicon material particles. The vibrator can vibrate the bucket to prevent blockage.

[0015] 2. The silicon material can be moved by setting a slider, a high-frequency spring and a blade. The device can make the slider move up and down in the guide groove of the bucket barrel through the vibration of the bucket barrel, so that the blade can move the silicon material, thereby improving the screening effect of the silicon material and ensuring the uniformity of silicon material feeding. At the same time, the elastic force design of the high-frequency spring can improve the movement effect of the slider. An inclined edge is provided under the guide groove of the bucket barrel to guide the silicon material and avoid a large amount of silicon material remaining in the guide groove of the bucket barrel.

[0016] 3. By setting up a suspension assembly and a hydraulic cylinder, convenient adjustment of the silicon material feeding position can be achieved. The device can suspend the negative pressure suction cylinder through two buckles. The electric valve can be moved to the top of the processing equipment through the extension and retraction of the piston rod end of the hydraulic cylinder, so that the negative pressure suction equipment can adapt to the height of the processing equipment. A handle end is set on the side of the negative pressure suction cylinder. The negative pressure suction cylinder can be pulled by holding the handle, so that the wheel end of the hanging wheel can move in the guide groove of the beam plate, and then the silicon material feeding position of the electric valve can be offset and adjusted to ensure the accuracy of the refined silicon material in the unloading and avoid the omission of silicon material.

[0017] 4. The suspension design of the negative pressure suction cylinder can be realized by setting the ring end design at the top of the frame group and the beam plate. The device can separate the fixed block from the side plate by removing the bolts between the fixed block and the side plate, and remove the bolts at the end of the hydraulic cylinder from the beam plate. At this time, the top plate can be pulled out, and the feeding adaptability of the negative pressure suction equipment can be improved by matching the hanging rope with the ring end at the top of the beam plate, which can further meet the needs of silicon material feeding and processing.

[0026] A guide groove is provided on the inner wall of the bucket tube 184 , and a slider 185 is movably installed inside the guide groove. A vane 187 is connected to the inner side of the slider 185 . A high-frequency spring 186 is connected to the top of the slider 185 , and the top of the high-frequency spring 186 is fixedly connected to the inner wall of the guide groove of the bucket tube 184 .

[0027] The blade 187 is designed to be inclined, the bottom end of the guide groove of the bucket tube 184 is designed to be an inclined surface, and the left and right blades 187 are symmetrically arranged.

[0028] A groove is provided at the bottom end of the beam plate 31, and a track plate end is provided on the inner wall of the groove. Two hanging wheels 34 are movably installed on the surface of the track plate end of the beam plate 31. The bottom ends of the two hanging wheels 34 are connected to a connecting plate 33. The bottom end of the connecting plate 33 is connected to a supporting plate 35, and the inner side of the bottom end of the supporting plate 35 is connected to a buckle ring 36. The buckle ring 36 is buckled to the surface of the negative pressure suction device 1 through an annular groove. The left and right sides of the buckle rings 36 are fixed by long rod bolts 37. An insert plate 38 is connected to the inner side of one of the connecting plates 33, and the insert plate 38 is inserted into the other connecting plate 33 through a slot.

[0029] A ball end is embedded in the ball groove on the outer side of the limit block 32 , and a guide groove matched with the hanging wheel 34 is opened at the top end of the rail plate end of the beam plate 31 .

[0030] The frame assembly 5 includes a base 51, and side panels 52 are symmetrically arranged on the left and right sides of the top of the base 51, and the top of the side panels 52 is covered with a top panel 54, and fixing blocks 53 are arranged on both sides of the bottom of the top panel 54, and the fixing blocks 53 are fixed to the inner walls of the side panels 52 by bolts.

[0031] The guide groove on the inner wall of the side plate 52 can guide the limit block 32, so that the beam plate 31 can move up and down stably inside the side plate 52 to prevent the beam plate 31 from shaking during movement. At the same time, the height of the beam plate 31 can be adjusted by telescoping the piston rod end of the hydraulic cylinder 4, thereby facilitating the lifting and changing of the height of the negative pressure suction cylinder 11, so that the bottom end of the docking cylinder 12 can adapt to the opening of the silicon material processing equipment. The annular groove design on the outer side of the docking cylinder 12 can cooperate with the buckle plate 14, so that the cover plate 15 can be hooked on the outer side of the docking cylinder 12, and the cover plate 15 can protect the lower leakage port at the end of the docking cylinder 12 to prevent the silicon material from scattering to the surrounding side during the fall, which plays a role in gathering materials to a certain extent. The silicon material can be pre-filled through the hopper 22, and the end of the transmission pipe 21 is located at the bottom of the hopper 22. After the negative pressure suction pump 16 is started, negative pressure suction is performed, which can facilitate the staff to freely adjust the suction volume according to the required silicon material feeding needs.

[0032] Through the design of the vibrator 188, the bucket 184 can be controlled to vibrate after the vibrator 188 is started. The bucket 184 can intercept large particles of silicon material in the silicon material, so that uniform particles of silicon material can fall after being screened by the bucket 184, thereby ensuring the particle uniformity of the silicon material. The slider 185 can be guided by the guide groove of the bucket 184, so that the slider 185 can move freely in the guide groove on the inner wall of the bucket 184. When the bucket 184 vibrates, the slider 185 can move up and down in the bucket 184. At the same time, the elastic force of the high-frequency spring 186 can improve the shaking effect of the slider 185. The movement of the slider 185 can drive the blade 187 to move, and then control the blade 187 to fluctuate the silicon material, so as to facilitate the flipping and screening of the silicon material, thereby ensuring the uniformity of the unloading particles. Through the design of the inclined surface of the guide groove of the bucket 184, the silicon material in the guide groove can be guided so that the silicon material can slide back into the bucket 184.

[0033] By setting the blade 187 in an inclined manner, the silicon material can be scooped up to avoid accumulation of the silicon material and influence on the screening effect of the silicon material. When the hanging wheel 34 moves on the track plate end surface of the beam plate 31, the negative pressure suction cylinder 11 can be adjusted so that the negative pressure suction cylinder 11 can be displaced, and the offset position of the silicon material unloading can be changed to ensure the accuracy of the silicon material when the processing equipment is fed. The long rod bolt 37 passes through both sides of the buckle 36, and the two buckle rings 36 cooperate with each other to be buckled on the outside of the negative pressure suction cylinder 11, thereby realizing the suspension operation of the negative pressure suction cylinder 11. The wheel end of the hanging wheel 34 rolls on the track plate end surface of the beam plate 31, which can ensure the smoothness of the negative pressure suction cylinder 11 during movement.

[0034] A grip end is provided on the side of the negative pressure suction cylinder 11, which is convenient for the staff to pull and adjust the negative pressure suction cylinder 11. The slot design of the plug plate 38 and the connecting plate 33 can increase the bearing strength of the two connecting plates 33 to avoid deformation of the buckle 36 during clamping and falling. When the limit block 32 is displaced in the guide groove on the inner wall of the side plate 52, the limit block 32 can drive the ball end to roll to ensure the smoothness of the up and down movement of the beam plate 31. The guide groove of the beam plate 31 can limit the hanging wheel 34 to ensure the smooth movement of the hanging wheel 34 A rail groove is opened on the rail plate end surface of the beam plate 31, which can further guide the movement of the hanging wheel 34 to ensure the stable displacement of the hanging wheel 34. The fixing block 53 is fixed to the inner wall of the side plate 52 by bolts. The bolts can be removed when necessary, and then the fixing block 53 is separated from the side plate 52, so that the top plate 54 can be removed after the piston rod end of the hydraulic cylinder 4 is separated from the beam plate 31. At this time, the design of the lifting ring ends on both sides of the top of the beam plate 31 can facilitate the staff to suspend the beam plate 31 in specific occasions.

[0035] The model of the negative pressure suction pump is 2RB-810-7500, and the model of the vibrator 188 is NTS 250NFL. Under the same conditions, they can also be replaced with other models.

[0036] Working principle: According to the attached Figure 2 With attached Figure 3 As shown, during use, one end of the transmission pipe 21 can be docked with the bottom end of the hopper 22, so that the left side of the transmission pipe 21 is docked with the right feeding end of the negative pressure suction cylinder 11, and the negative pressure suction pump 16 is started to suck, so that negative pressure is formed inside the negative pressure suction cylinder 11, and the silicon material is extracted from the hopper 22 into the negative pressure suction cylinder 11, and the silicon material falls to the surface of the bucket tube 184. After the vibrator 188 is started, the bucket tube 184 is driven to vibrate on the surface of the support spring 183, and then the silicon material is screened, and the silicon material falls to the surface of the electric valve 13. When the silicon material fills the bin of the docking tube 12, the electric valve 13 can be opened. At this time, the silicon material falls, thereby completing the feeding operation. Figure 4 With attached Figure 5 As shown, when the bucket 184 vibrates, the slider 185 can move in the guide groove of the bucket 184, and the slider 185 can drive the blade 187 to move up and down, and then perform a toggling operation on the silicon material to accelerate the screening effect of the silicon material; Secondly, according to the attached Figure 6 With attached Figure 7 As shown, the hydraulic cylinder 4 is started, and the piston shaft end of the hydraulic cylinder 4 can be telescopically moved to push the beam plate 31. The beam plate 31 can change the height of the negative pressure suction device 1 during the descent. When the bottom opening of the docking tube 12 deviates from the inlet of the processing equipment, the grip end of the negative pressure suction cylinder 11 can be held and pulled to make the negative pressure suction cylinder 11 drive the support plate 35 to move, and the support plate 35 can drive the connecting plate 33 to move, and then the hanging wheel 34 is controlled to move on the track plate end of the beam plate 31 to ensure the accuracy of the silicon material inside the transmission tube 21 falling into the processing equipment.
